That quote in the headline appeared in a Trump campaign fund raising email as noted in a May 23, 2024 AP article.
That claim by Trump, of course, is an outright lie.
Trump's entire campaign has been about stoking violence. Not a single Republican has suggested he stop. Biden makes one innocent quip about putting Trump in the bullseye, and the Republicans react with feigned horror and disbelief.
Trump outright lied about the FBI search for stolen documents an Mar a logo (he wasn't even there at the time) to make it sound as if Biden wanted him dead. He fundraised off of the lie. His campaign and supporters were fine with it. No Republicsn spoke out against it.
He primed his base to believe Biden was trying to kill him, and then we have the unforseen assassination attempt.The attempt on Trump's life has been quickly and soundly denounced by Democrats, but it will fall on deaf Republican ears.
Where Trump's ang his MAGA supporters’ future rhetoric takes us is unforseen, but we are in stotmy, unchartered waters.
